Modern & Contemporary Art
Working with the former Global Heads of the Impressionist & Modern department at a leading auction firm, we facilitated the negotiated auction consignment of a significant Impressionist & Modern art collection, valued at over $40 million, in a competitive bid process with two major international auction firms for the Fall 2017 season, and in the end secured a confidential global guarantee and substantial “hammer bonus” for the East Coast estate.
· On behalf of a former Ambassador to Nigeria in the 1960s, we arranged for the consignment of a major early oil on canvas by Ben Enwonwu, breaking a record for a painting by this artist at the time and achieving 250% of the pre-sale estimates.
· On behalf of a consignor in Maryland, we arranged for the auction consignment in Hong Kong of a significant vase from the Yongzheng period in China, realizing just over $9.4 million for the client.
· On behalf of an estate with a substantial collection of Japanese decorative arts, we negotiated the donation of a segment of the collection with an appropriate art museum with collecting strengths in the field, as well as the consignment of the remainder at a major auction house, achieving both the philanthropic and fiduciary goals of the decedent for the executors.
